Purpose: The aim of this descriptive study was to identify factors influencing quality of life among family caregivers of non-cancer patients at the end-of-life stage. Methods: A cross-sectional survey was conducted using a questionnaire. Participants included 172 family caregivers caring for non-cancer patients. Data were collected from April to May 2016 and analyzed with descriptive statistics, an independent t-test, one-way ANOVA, Pearson's correlation coefficient, and a hierarchical regression analysis using the SPSS/WIN 24.0 program. Results: The mean of the participants' quality of life was 51.70±9.98. Factors influencing quality of life among family caregivers were spiritual care (𝛽=-.45, p=.021), coordination among family members or relatives (𝛽=-.27, p=.029), and psychological support (𝛽=-.04, p=.031). The explanatory power of the model was 21.0%. Conclusion: The findings of this study suggest that care needs; spiritual care, coordination among family members or relatives, and psychological support are important factors for family caregivers' quality of life. To improve quality of life among family caregivers who are taking care of non-cancer patients at the end-of-life stage, national systems establishing comprehensive support considering the respective care needs of patients are crucial.

Purpose: The purpose of this study was to explore factors affecting uncertainty and general well-being based on Uncertainty in Illness Theory. Methods: Data were collected from 125 outpatients who had received hemodialysis. The path model among four concepts, such as period of hemodialysis, social support, uncertainty, and general well-being, was tested. Tangible support, positive social interaction, affectionate, and emotional/informational support were measured as social support. Adaptation in the model was operationalized as general well-being which consisted of anxiety, depression, positive well-being, self-control, and general health. Results: All paths were statistically significant at the level of ${\alpha}$=.05. The significant paths were the path from period of hemodialysis to uncertainty (t=-2.86), social support to uncertainty (t=-2.01), uncertainty to general wellbeing (t=-2.85), and social support to general well-being (t=3.55). Conclusion: Patients who perceived low uncertainty and high social support were likely to feel well-being. Therefore, nurses should give patients appropriate information according to their needs and have meaningful interaction with patients to reduce their uncertainty and render social support.

Vapnik의 통계적 학습이론은 분류, 회귀, 그리고 군집화를 위하여 SVM(support vector machine), SVR(support vector regression), 그리고 SVC(support vector clustering)의 3가지 학습 알고리즘을 포함한다. 이들 중에서 SVC는 가우시안 커널함수에 기반한 지지벡터를 이용하여 비교적 우수한 군집화 결과를 제공하고 있다. 하지만 SVM, SVR과 마찬가지로 SVC도 커널모수와 정규화상수에 대한 최적결정이 요구된다 하지만 대부분의 분석작업에서 사용자의 주관적 경험에 의존하거나 격자탐색과 같이 많은 컴퓨팅 시간을 요구하는 전략에 의존하고 있다. 본 논문에서는 SVC에서 사용되는 커널모수와 정규화상수의 효율적인 결정을 위하여 차분진화를 이용한 DESVC(differential evolution based SVC)를 제안한다 UCI Machine Learning repository의 학습데이터와 시뮬레이션 데이터 집합들을 이용한 실험을 통하여 기존의 기계학습 알고리즘과의 성능평가를 수행한다.

College students experience more cyber bullying than youth and cyber bullying on college students may be more harmful than youth. But many studies of cyber bullying have been conducted in youth, but little has been studied for college students. Therefore, this study investigated the negative effects of college students' cyber bullying experience on cognitive processing ability and emotional states. The social support of friends has a buffering effect that prevents stress and reduces the influence on external damage in stressful situations. But the impact of parental social support is controversial. Traditionally, the social support of parents has been claimed to mitigate the negative effects of external damage. Recently, however, it has been argued that parental social support, without considering the independence and autonomy needs of college students, does not alleviate the negative effects. Therefore, this study examined how the social support of friends and parents moderate the negative impact of cyber bullying. The results show that the more college students experience cyber bullying, the lower their cognitive processing ability and emotional states. And, the higher the social support of friends, the lower the harmful impacts of cyber bullying on cognitive processing ability and emotional states. But, the higher the social support of parents, the higher the harmful impacts of cyber bullying on cognitive processing ability and emotional states.

The purpose of this study was to develop the framework for the relapse prevention program. The study examined interventional needs for a relapse prevention program among adult substance abusers. The total of 107 adult substance abusers were surveyed and asked about their interventional needs for the relapse prevention program. The questionnaire was developed by the researcher on the basis of several theories such as problem behavior theory, ecologica1-developmental theory, social support theory, and coping theory. Results showed that admit substance abusers wanted the program to deal with such issues related with individual, family, social skills, and drugs. The implications of study findings were discussed.

This study investigated Korean science teachers' concerns and needs regarding inquiry testing to cope with the innovation called College Scholastic Abilities Test(CSAT), which was officially first administered as the nation-wide college entrance exam in 1994. This study adopted Concerns Based Adoption Model(CBAM) as the theoretical framework developed by Hall et al. 60 high science teachers (30 physics, 20 earth science, 10 others) were involved for the main study in August, 1992. In general. science teachers demonstrated a concern profile similar to that of 'nonusers'. They showed high level of concerns on the 'information' and 'personal' stage, while low level of concerns on 'management' and 'consequence' stage. Science teachers expressed their strong needs for knowledge and support to facilitate inquiry teaching and testing, text books written in inquiry mode. It is recommended that in-service trainings be provided based on the concerns and needs of teachers for a better teacher training and successful implementation of the innovation.

The main factors of radar signals used in electronic warfare are Radio Frequency(RF), Pulse Repetition Interval(PRI), Pulse Width(PW), Scan Parameter(SP) and so on. This radar signals may have some important information for the electronic warfare. So, there is a necessity for making a threat database to decide whether the radar signal is a threat or not. When the electronic support system collects some threat radar signals, it needs the search band to control the receivers and filter banks of the system. In this paper we propose search band implementation considering the type and center frequency of the receivers of the electronic support system.

Purpose: In Korea, the prevalence of dementia patients has increased, which makes the care burden of nurses important. The purpose of this study is to identify factors affecting the care burden of nurses caring elderly patients with dementia. Methods: A cross-sectional design was conducted using a convenience sample of 127 nurses from two hospitals and a nursing home in Korea. Participants completed questionnaires on knowledge of and attitudes toward dementia, social support, self-esteem, dementia problematic behavior (DPB), and professional caregiver burden index. The data were analyzed by using the t-test, ANOVA, Pearson correlation, and multiple regression with the SPSS/windows version 21.0 program. Results: The influencing factors for nurse burden include day shift, DPB, self-esteem, social support, which explain 28.0% of care burden of nurses. Conclusion: To reduce the burden of the nurses, there needs to be an administrative system that focuses on enhancing their self-esteem and social support. Active institutional support may be necessary for the nurses taking care of elderly patients with dementia.
